| description | An aluminum alloy brazing sheet exhibits excellent brazability by effectively weakening an oxide film formed on the surface of a filler metal. The aluminum alloy brazing sheet includes a core material and a filler metal, and is used to braze aluminum in an inert gas atmosphere or in vacuum, the core material including aluminum or an aluminum alloy, the filler metal including 6 to 13 mass % of Si, with the balance being Al and unavoidable impurities, and one side or each side of the core material being clad with the filler metal, wherein the core material is clad with the filler metal in a state in which a sheet material is interposed between the core material and the filler metal, the sheet material including one element, or two or more elements, among 0.05 mass % or more of Li, 0.05 mass % or more of Be, 0.05 mass % or more of Ba, and 0.05 mass % or more of Ca, with the balance being Al and unavoidable impurities. |
